One of my friends has been hitting his chest and arms twice a week for a while now (I'm gonna say for 2 months now), and he's seeing great results! His bench has increased tremendously, now when I work out with him he leaves me in the dust in pretty much everything. Only problem that's ALL he does all week, he looks like those cartoon characters with the HUGE upper body and tiny legs (seriously, he never does legs) I like to think I have a more proportional look. However, this got me thinking, is hitting the same muscle twice in a week really beneficial or are there serious drawbacks to it? I know some of you guys train week in and week out like that, but I honestly don't know if I could handle that much in a single week. What's your guys' opinions/experiences?
